What's the purpose of being a Star Alliance airline member?

Star Alliance is the world's first and largest airline alliance, Star Alliance would be serving 720 destinations in 110 countries with a combined fleet of 1,650 aircraft. In 1997, a group of five world-class airlines got together to create something never seen before - an alliance that brings together networks, lounge access, check-in services, ticketing and dozens of other services to improve the travel experience for customers. “Executing leadership in managing a portfolio of alliance products and services using an agreed process.” Star Alliance member airlines fly to more destinations than the competition – and that means easier travel and quicker connections. The main goal has always been to make the travel experience smoother. So the member airlines are located closer together in airports, introducing new technologies, building common facilities at airports, coordinating schedules and installing connection teams for faster transfers. There are many other Star Alliance initiatives, and many more in the pipeline. An airline alliance is an agreement between two or more airlines to cooperate on a substantial level. Providing network of connectivity and convenience for international passengers and international packages. Alliances also provide convenient marketing branding to facilitate travelers making inter-airline codeshare connections within countries. This branding goes as far as to even include unified aircraft liveries among member airlines.
